In this paper, we present a novel Mutual Information (MI) based spatial frequency domain packet scheduling for downlink Orthogonal Frequency Division Multiple Access (OFDMA) multiuser MIMO systems. The proposed scheduler is designed to exploit the available multiuser diversity in time, frequency and spatial domains. The analysis model is based on the generalized 3GPP LTE downlink transmission for which two Spatial Division Multiplexing (SDM) multiuser MIMO schemes are investigated: Single User (SU) and Multi-user (MU) MIMO schemes. The results show that the proposed MU-MIMO scheduler is a more realistic solution and provides fairness among users for the system under consideration.
